Introduction
============

Description
-----------
Provides access to input variables in a convenient way, with security in mind.

Requirements
============
We all know that you should always check input variables, but PHP does not
offer really good functionality for doing this in a safe way. The User Input
component is meant to address this issue by implementing a set of filters and
mechanisms that users can use to safely access their input data.

Design goals
============
User Input handling is greatly improved in PHP, where there is a special filter
extension to get to user inputted data. Although it's much easier than before
for handling with user input in a secure way, it doesn't provide a very nice
interface. This component is addressing this.
